Title: Scavenging valve and charging device for diesel engine
Inventor: OOBA HIDEO
IPC: F02B39/00
Filed: 1980-10-09
Abstract: PURPOSE: To prevent a damage on a scavenging valve and reduce a pressue loss by making up a part or all part of a valve plate of the scavenging valve and connecting a scavenging trunk between the scavenging valve and an engine.  
     CONSTITUTION: A scavenging duct 2 connects an exhaust trunk 11 to exhaust turbosupercharger 1 which directly combines an exhaust turbine 1a with a comressor 1b. A valve plate 9 of an exhaust valve 8 is made up of a bimetal 9a and an auxiliary blower 5 is disposed outside of a scavenging duct 2. As the temperature of an exhaust gas grows higher, the valve plate 9 is moved more away from a valve seat 10 to reduce a vibration caused by a flowing air and an impact given by it on the valve seat 10, thereby preventing a damage resulting from a fatigue of the valve plate 9. In the normal operation, the scavenging valve 8 is fully opened so that a pressure loss may be reduced.

Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To reduce detection errors of a torque sensor caused by a size accuracy and an assembling error of slits by arranging the slits so that a part forming an overlap part of the slits is shorter than a straight part. SOLUTION: A length L1 in a diametrical direction of an output axis slit 34a is made larger than a length L2 in a diametrical direction of an input axis slit 32a at input output slit plates 32, 34. A part 34c forming an overlap part A of a side 34b is set shorter than a length of the side 34b which is a straight part. A change in area of the overlap part A to a shift of the slits in a specific direction is reduced accordingly. Even a minute size error at the straight part does not actually change the area of the overlap part A. In other words, a torque detection error to at least the size error of one slit can be reduced. Even if two slits minutely shift in a direction of the straight part, the area of the overlap part A does not change actually and the detection error is reduced.
